AEI is a leader in the material handling industry, producing both stationary and portable equipment. From stand-alone screens to complete plants, all AEI equipment is manufactured in Leola, PA. The Eco-Star screen is a twist on the disc-star screen, with patented technology that resists wrapping of long stringy material. The heavy duty Hard-Ox design of the Eco-Star ensures long wear life and rugged performance. The bivi-TEC screen with its dynamic live deck resists blinding in wet sticky conditions, and is used for separating at much smaller openings than possible with conventional screens.
